E.ON Installs Electric Boilers in Székesfehérvár

E.ON Hungária Group is installing industrial-scale electric boilers capable of generating enough heat to heat nearly 1,500 homes annually in the district heating system of Székesfehérvár. The aim of the investment, worth more than HUF 4 billion, is to support the greening of Székesfehérvár by partially replacing fossil fuel-based heat generation.

E.ON is installing industrial electric boilers with a thermal output of 20 MW and 5 MW at two locations. An insulated heat storage tank with a water volume of 1,500 cubic meters will also be built at the Bakony Street site, enabling the efficient use of the heat generated by the electric boilers. The heat storage tank, which is 13 meters in diameter and 13 meters high, will ensure that the energy generated by the boilers can be used on a scheduled basis during peak loads in the district heating system, i.e., in the morning and evening.

The equipment generates heat from electricity instead of fossil fuels, and E.ON also provides a guarantee of origin for part of the green electricity. The planned annual heat production of the electric boilers is 22,000 GJ (gigajoules), which corresponds to the annual heating requirements of approximately 1,500 homes. The boilers and heat storage facilities can be controlled remotely, and their operation also contributes to ensuring the balance of the electricity system.

The city's district heating provider, Széphő Plc., has signed a long-term, 10-year contract with the E.ON Group for the construction and operation of the electric boilers and heat storage facilities. The total cost of the investment – EUR 10 million, equivalent to approximately HUF 4 billion – will be covered by E.ON. The project is currently in the preparation and planning phase, with construction scheduled to begin in spring 2026 and be completed in the first half of 2027.

"We are constantly working to make the equipment necessary for the operation of the city more modern and environmentally friendly, and SZÉPHŐ is also of paramount importance in this area. The heating and hot water supply of thousands of homes and dozens of public institutions in Székesfehérvár depends on the stable operation of the company. In addition to providing a reliable service, we have always strived to ensure that existing systems operate as economically as possible. The developments implemented by the company over the past decade have all served this purpose, as it was necessary to find solutions to the challenges posed by the energy crisis as quickly as possible in the interests of the residents of Székesfehérvár. Energy costs are a significant item in a city's budget, which is why stability in this area is important to us, but we are also looking for ways to make our energy and energy consumption portfolio as independent as possible from market extremes. The investment made by E.ON, with its state-of-the-art electric boilers and heat storage system, is well aligned with Székesfehérvár's environmental goals," said Dr. András Cser-Palkovics, mayor of Székesfehérvár, at the press event announcing the investment.
